Greasable bolt for stock bushing???

87 V1500

52" stock springs in the rear. New from SD truck spring.

Does your greasable bolt work with stock application? It seems to be a metric as it is just a tad bigger than the 1/2 bolts in the hardware store. Non of the SAE bolts at Lowes we exactly the same.

Rear shackle bolt is all I need...

Normally the center sleeve is bonded to the rubber bushing, as the bushing is bonded to the outer steel sleeve. Greasing won't do anything unless the sleeve has torn free, and if that's the case it'll need to be replaced.

Ok, after more investigation it's a 9/16 bolt with 13/16 head.
